VM

Product catalog summary

Overview: The VM Micro Switch is designed for long life and high efficiency, offering a dielectric strength of 2000V due to its long creeping distance between terminals and earth. It is available in various configurations to suit different applications, from low energy circuits to high capacity uses.

Specifications: The switch features SPDT (Single Pole Double Throw) contacts with options for silver or gold-plated silver contacts. It supports electrical ratings of AC125V, 250V at 15A for resistive loads and offers insulation resistance of more than 100MΩ at DC 500V. The dielectric strength is AC 1000V between NC and NO terminals and AC 2000V between terminals and ground.

Mechanical and Electrical Life: The switch is rated for a mechanical life of up to 10,000,000 operations and an electrical life of 100,000 operations at rated load. It operates within a temperature range of -15°C to 70°C and a maximum humidity of 80% RH.

Operating Characteristics: The switch is available with different operating forces (OF) ranging from 0.10N to 3.92N, and various actuator types including pin plunger, standard hinged lever, short hinged lever, long hinged lever, and simulated hinged lever.

Handling and Installation: When soldering, a maximum of 60W iron should be used for no more than 5 seconds to avoid damaging the switch body. For mounting, M3 screws with flat/spring washers are recommended, and insulation cloth should be used when mounting on metal bodies.

Ordering Information: The ordering code includes options for contact rating, terminals, contact materials, and actuator types. Specific combinations are available as standard types, with a minimum order requirement for non-standard combinations.

VM ORDERING CODE •Silver/Gold plated silver contact Note)Terminal for W/E Alloy #1 Cross-bar contact is #187 Tab/Solder terminal only. HANDLING HINTS 1. When soldering iron of max. 60W for a maximum of 5 seconds on any terminals be careful to ensure that the iron does not touch the switch body. 2. When fixing, use M3 screw and flat/spring washer and fix firmly. Moderate fixing torque is 0.588N-m j6kg-cml . 3. When mounting on metal body, it is recommended to use insulation cloth between switch and panel. We provide exclusive insulation cloth for VM switch.
