Door Exit Release Button
The YINGHUA Z30 is a zinc-alloy push switch designed for access-control systems on all kinds of doors. It provides a momentary normally-open contact to trigger an electric lock or strike when pressed. Installers and facility managers use it for secure egress in commercial and residential entryways. The unit mounts flush on a gate or door frame for indoor or sheltered outdoor use.
Contact rating 3A at 36 VDC
The single specification that determines compatibility is the output contact rated at 3 amps and 36 volts DC maximum. The switch supplies a dry normally-open and common pair, so the access controller or lock power supply must stay within this voltage and current limit. Exceeding either value will damage the contacts and void reliable operation.
Operating range -20 to +55 °C
The button is rated for continuous operation from -20 °C to +55 °C (14 °F to 131 °F) in humidity up to 95 % RH. Mechanical life is tested to 500 000 cycles with no forced-air cooling or active components, so acoustic noise is limited to the tactile click of the actuator. Power draw is negligible because the switch passes only the control signal to the downstream lock circuit.

Questions about this item
What does the 500000 cycle rating mean for daily use?
The switch is tested to 500000 mechanical operations, so it will last years in a typical access-control installation.
What does the 3A 36VDC contact rating limit in practice?
The NO/COM contacts can switch up to 3 amps at 36 volts DC, capping the load you can drive directly from the button.
What mounting clearance does the zinc-alloy panel need?
The metal panel is designed to fit standard door-access cut-outs; check the cut-out dimensions against your door prep before installing.
