Micro switch Promet T0-MK1MIM2 — 1 NO + 1 NC contacts, long lever with roller

The Promet T0-MK1MIM2 micro switch is a precision-engineered component designed for reliable electrical switching in industrial and automation environments. Featuring a configuration of one normally open (1 NO) and one normally closed (1 NC) contact, this device ensures versatile connectivity for various control circuits. The switch is equipped with a long lever and an integrated roller, which facilitates smooth mechanical actuation when triggered by moving parts, cams, or machine components.

Advantages

This micro switch offers high durability and consistent performance in demanding operational conditions. Its compact design allows for easy integration into space-constrained control panels and machinery housings. The inclusion of both NO and NC contacts provides flexibility for different logic requirements in automation systems. The long lever with a roller minimizes friction during contact, extending the mechanical lifespan of the switch and ensuring accurate detection of position or end-stop limits.

Suitable for

• Industrial automation systems
• Control panels and switchgear
• End-stop detection in machinery
• Position monitoring for moving parts
• Safety interlock applications

When it may not be suitable

This switch is not intended for high-power direct load switching, such as powering large motors or heavy heating elements directly. It is designed for control-level signals and should be used in conjunction with contactors or relays when managing high-current applications.

Key specifications

• Contact configuration: 1 NO + 1 NC
• Actuator type: Long lever with roller
• Application: Mechanical position sensing and control
• Design: Compact industrial housing

How to use

Installation should be performed by qualified personnel in accordance with the electrical schematic of the equipment. The switch is mounted using the provided fixing holes, ensuring that the lever is positioned correctly to be actuated by the target mechanical component. Ensure that the travel distance of the actuator does not exceed the mechanical limits of the switch to prevent damage. Wiring should be connected to the corresponding terminals for the desired NO or NC logic.

What to consider before purchase

• Verify the physical space available for the lever movement.
• Ensure the electrical ratings of your control circuit match the switch specifications.
• Check the mechanical force required to actuate the roller lever.

Usage recommendations

Regularly inspect the roller and lever for signs of mechanical wear or debris accumulation to ensure consistent operation. Periodically verify that the electrical connections remain tight and free from oxidation.
