Product details
The PG-03B safety seat switch is a high-quality safety switch designed by YESWITCH specifically for rideon mowers, garden machinery, golf carts, and similar equipment. As a normally open plunger switch in the PG series, the PG-03B has become a widely adopted safety component among global mower manufacturers thanks to its excellent durability, reliable momentary return function, and simple snapfit mounting design. The product carries both CE and UL international certifications and is a perfect replacement for the Delta 6520 series, offering customers a costeffective safety solution.

Product Features
Momentary Return Function – Enhanced Safety
The PG-03B adopts a momentary return design and is a normally open plunger switch. When the seat is not depressed, the seat safety switch remains in the open (OFF) state. Once the seat is pressed down, the plunger is triggered and the switch immediately closes (ON). When the operator leaves the seat, the switch automatically returns to the open state, effectively preventing accidental operation and ensuring equipment safety at all times. This design ensures the machine can only start or keep running when the seat is safely occupied, making it a critical safety mechanism for seat sensors.
 
 
Plunger Structure – Sensitive and Stable Response
The plungertype mechanical trigger structure provides a clear actuation travel and definite tactile feedback. The lawn mower switch operating force is approximately 1600gf ±300gf, with an operating travel of about 9.5mm ±1.0mm. Each press delivers stable trigger feedback. The plunger is made of PBT, the housing and body are made of PP material with UL 94V2 flammability rating, and the terminals are brass with gold plating, ensuring excellent conductivity and corrosion resistance.
 
ExtraLong Service Life – Durable and Rugged
The PG-03B push button seat switch offers outstanding durability, with an electrical life exceeding 10,000 cycles and a mechanical life exceeding 75,000 cycles. Whether in low or high temperatures, the PG-03B performs reliably even under heavy workloads. The operating temperature ranges from -40 to 85 degrees, and it withstands a 96hour salt spray test, making it suitable for various harsh weather conditions.
 
SnapFit Mounting – Saves Time and Effort
The PG-03B features a snapfit mounting design that requires no tools for installation or removal, greatly improving installation and maintenance efficiency. Users simply plug the mating connector from the seat harness into the switch for quick integration into a wide range of applications.
 
 
Application Scenarios
The PG-03B safety seat switch is widely used in the following fields:
Rideon mowers – As the primary safety detection switch under the seat, commonly used on rideon and commercial mowers to ensure operator safety.
Golf carts – Used for operator presence detection in golf carts, preventing unintended movement when the vehicle is unattended.

Why Replace the Delta 6520 Series?
The PG-03B plunger seat safety is fully compatible with the Delta 6520 series safety switch in function, dimensions, and performance, allowing it to directly replace Delta 6520 series products. The PG-03B interlock plunger safety switch not only maintains the same normally open function and momentary return mechanism as the Delta 6520 series, but also achieves industryleading levels of electrical and mechanical life – making it a more costeffective choice.
