Ricoh buton

Field technicians and electronics assemblers often need a dependable, momentary switch for control panels, test fixtures, and prototype boards. The Ricoh AW500027 push switch delivers consistent tactile feedback and reliable switching in a compact PCB-mount package. With its SPST-NO contact configuration and through-hole termination, it integrates easily into automated soldering processes and manual assembly alike.

Key specifications

• Switch type: momentary, SPST-NO (single pole, single throw, normally open)
• Contact rating: 12V DC, 50mA
• Actuator: round button, black, non-illuminated
• Mounting: PCB through-hole, PC pin termination
• Contact material: silver plated brass
• Operating force: 1.5 N
• Mechanical life: 100,000 cycles
• Electrical life: 50,000 cycles
• Operating temperature: -25°C to +70°C
• Insulation resistance: >100 MΩ
• Dielectric strength: 500V AC for 1 minute
• Body material: PBT (polybutylene terephthalate)

Why choose it

This switch is built for longevity in demanding environments. The silver plated brass contacts ensure low contact resistance and reliable performance over tens of thousands of actuations. The PBT body withstands high temperatures during soldering and provides excellent mechanical stability. Its standard footprint and PC pin layout make it a drop-in replacement for many common tactile switches, reducing design time and inventory complexity.

Ideal use cases

• Industrial control panels and operator interfaces
• Test and measurement equipment
• Consumer electronics and appliances
• Prototyping and educational electronics
• Automotive diagnostic tools

Good to know

The AW500027 is non-illuminated and features a black actuator, blending seamlessly into dark or neutral front panels. It is rated for low-voltage, low-current signal switching, making it ideal for logic-level inputs rather than power loads. For automated assembly, the through-hole design is compatible with wave soldering processes. Always verify the PCB hole pattern matches the pin spacing before production.
