Product details

YESWITCH J-213E is a 4-pin one-piece dedicated safety switch. It is a built-in NO+NC Dual-contact Safety Switch and is integrated with signal output. The Interlock Plunger Seat Safety Switch is suitable for parking brake detection and seat entry sensing scenarios in electric vehicles, golf carts, garden machinery, and special vehicles. The contacts are stable when conducting, the sensing is sensitive, it is resistant to vibration and aging, and the installation is highly adaptable. The Lawn Tractor Safety Switches can simultaneously output two status signals, meeting the requirements for equipment safety interlock and start-stop control circuits.

Product Features

1. Interlock Plunger Seat Safety Switch Structural and Appearance Features

- Compact integrated design: black flame-retardant shell + gray top plunger, side snap-in installation structure, compatible with standard panel holes, secure and convenient to install.

- Complete protective accessories: matching multi-layer pleated rubber dustproof and waterproof cover + 4-pin wiring socket, effectively resisting outdoor dust, rain, and oil contamination.

- 4-pin straight-through solder pads: gold plated brass pins, stable conductivity, compatible with both PCB soldering and wire harness insertion installation methods.

2. NO+NC Dual-contact Safety Switch Electrical and Functional Features

- NO+NC dual-contact output: normally closed (NC) conductive when in the off position, normally open (NO) when on, the state reverses after the piston is pressed down, capable of simultaneously outputting two mutually exclusive signals, meeting safety interlock requirements.

- Instant reset trigger: spring self-resetting piston design, sensitive, automatically rebounds after release, ensuring real-time and reliable status feedback.

- Wide load compatibility: rated load 5A 125VAC / 3A 250VAC, compatible with 12V/24V DC vehicle systems and low-voltage AC control circuits. (About high current switch, YESWITCH HT802 Series Toggle Switches are also perfect choices)

3. Interlock Plunger Seat Safety Switch Reliability and Environmental Advantages

- High protection level: IP65 dust and water resistance, can operate stably in a wide temperature range of -40℃ to +85℃, resistant to outdoor vibration and impact. (Our Waterproof Toggle Switch has an IP68 protection rating.)

- Long service life design: mechanical life ≥ 75,000 times, electrical life ≥ 10,000 times, flame-retardant material complies with REACH environmental standards, long-term use without safety hazards.

- Strong anti-interference ability: dual-contact structure avoids single-point failure risk, suitable for equipment scenarios with extremely high safety requirements.

Application of the Lawn Tractor Safety Switches

1. Golf cart / Electric sightseeing vehicle

- Parking brake inspection: Check if the parking brake lever is in place. If not, the vehicle cannot start to prevent rolling away or driving with the gear engaged.

- Safety interlock control: Cooperate with the vehicle control system to achieve the safety logic of "no parking, no gear engagement", enhancing driving and riding safety.

2. Garden machinery (riding lawn mowers, lawn vehicles)

- Safety seat occupancy sensor: Detect if the driver is seated on the seat. When no one is on board, automatically cut off the engine / motor power to prevent the equipment from losing control and injuring people.

- Operation status interlock: Linked with the blade clutch and the traveling system, only when the driver is present can the working components be started.

3. Construction machinery and special vehicles

- Small construction machinery: Such as the cab position detection of small loaders and excavators, and the feedback of handbrake / parking status.

- Agricultural machinery: Seat safety interlock and parking brake signal output for tractors and harvesters.

- Material handling equipment: Parking brake detection and driver in-seat safety control for forklifts and stackers.

4. Other industrial safety scenarios

- Equipment door / cover safety detection: As a safety door switch, detect if the equipment protective door is closed. If not closed, prohibit the equipment from running.

- Position limit detection: Travel limit of automated equipment, output of position arrival signal.

FAQ about the Interlock Plunger Seat Safety Switch

Q1: What are the functions of the 4 pins respectively? A1:

2 Public terminals (COM): Corresponding to the common terminals of the NO and NC circuits respectively

1 Normally Open contact (NO): Opened in normal state, closes when the plunger is depressed

1 Normally Closed contact (NC): Closed in normal state, opens when the plunger is depressed.

Q2: How much current and voltage can it handle?

A2: The rated load is 5A at 125VAC / 3A at 250VAC. It can also be compatible with 12V/24V DC vehicle systems, suitable for low-voltage control circuits. It is not recommended to directly drive high-power loads.

Q3: What are the triggering and resetting methods?

A3: Triggering: The plunger is pressed down

Resetting: The spring automatically returns to its original position. Once released, the plunger rebounds and the contact state returns to normal. This is a type of instantaneous switch without self-locking function.

Q4: How is the installation method?

A4: It is installed using a snap-on panel, compatible with standard holes. The 4 straight-through solder pads can be used for PCB welding or wire harness insertion. The accompanying rubber sheath can further enhance the protection performance.
