Micro-switches with lever to spring, 2 pieces, switch of end of course for device mechanical NO + NC 250VAC

Features:

1. SHELL IN PLASTIC PP: The micro-switch uses a shell in plastic PP, which is waterproof and resistant to the oil, with a resistance mechanical high and a good resistance to the impacts.

2. GOOD CONDUCTIVITY: Adoption of conductors in copper thick and of contact in silver, with a good conductivity, a low resistant, not d'arc and a more large capacity of load.

3. STRUCTURE of SEALING: The cover before rear and the body of the cylinder adopt a structure d'enveloppe of roll rivets, ensuring a strong performance of sealing, a connection stable and reliable.

4. Action mechanical : the micro-switch has action mechanical more soft and has wide range of actuator, including of style with positions d'action adjustable.

5. APPLICATION WIDE: Widely used in the strip carry, the ascenseurs, the parkings, the processing mechanical, the machines of packaging, the manufacturing of semi-conductors, etc.
