Introduction to Pressure Micro Switch

A pressure micro switch is a control element that combines a pressure sensing mechanism with a micro switch, designed specifically for the high-volume OEM market. Its function is to mechanically trigger an internal micro switch when the sensed pressure reaches a preset value, thereby connecting or disconnecting the circuit.

Features of Pressure Micro Switch

I. Pressure-Triggered Actuation: Pressure micro switches use pneumatic or hydraulic pressure to act on a diaphragm, piston, or bellows. When the pressure reaches a set threshold, the internal micro switch is triggered, controlling the circuit's on/off state.
II. Clear Snap Action Output: The pressure micro switch uses a snap action micro switch as its signal output unit. When the pressure reaches the actuation point, the contacts switch instantaneously, providing a clear, jitter-free signal and avoiding false triggering caused by pressure fluctuations.
III. Accurate and Repeatable Switching Point: Through precisely designed springs, diaphragms, and force transmission structures, the pressure micro switch possesses a stable actuation pressure point, excellent repeatability, and controllable hysteresis, ensuring that the equipment starts and stops under the same pressure conditions in every operation.
IV. Safety Protection Function: Pressure micro switches are often designed as safety interlocking elements. When abnormal pressure is detected, they cut off the heating or drive circuit, preventing the equipment from continuing to operate, and then trigger protection or alarm logic. This greatly avoids dry burning, overpressure, system damage, and even safety accidents.
