The R18-29A3 is a compact momentary push button switch designed for precision control in low-voltage AC applications. Featuring a round actuator and SPST-0-(1) contact form, this switch momentarily closes the circuit when pressed and opens when released-ideal for use in signal input, resets, or control panels.
Engineered for reliability, it supports up to 3A at 125VAC and includes solder-lug terminals for easy and secure installation. The small Ø9.5mm form factor makes it ideal for tight space constraints in electronics or panel designs.
