IMO Precision Controls devices with fitted reset facility, and when reset allows the device to trip when actuator is operated. The new device is a block inserted between the switch body and the head, and could be rotated independently, and positioned in any of the possible four. This new device has following advantages: The reset device can be integrated into almost all standard actuator heads with snap action are no longer necessary because the tripping movement is made by the reset device itself The reset device can be rotated independently from the head for maximum flexibility during installation Two driving forces: standard and increased for applications with vibrations Mechanical endurance: 1 million operating cycles.
