JAI JW LIMIT SWITCHES DUST AND DAMP PROOF
                                          
  
Non Plug-in Small Precision Limit Switches ore designed specifically for use on modern machine tools, to control starting, stopping or reversing of electrical motors including safety and signalling light, lifting gear, hoists, conveyors, etc.

The two pole limit switches are identical in appearance and size to the popular single pole version. Two pole limit switches are desirable in many installations and can reduce the number of limit switches and control relays used.

Protected against oil, cutting lubricants and fine dust penetration by using compressed rubber rings, special gaskets, pressure die cast zinc top and aluminium bottom cover.

All the parts are anti-corrosive material and paints.
Spring return, Snap action, Quick make and Quick break contacts.

1 N.O. 1 N.C. contactsare Single Pole, Double Throw‑one circuit normally open and one circuit normally closed. These Circuits are electrically separate, but cannot be used on opposite polarities.

2 N.O. 2 N.C. contacts: Each pole is electrically separate from the other and can be used on opposite polarities.

The contacts of each pole, double throw‑these circuits are electrically separate, but cannot be used on opposite polarities
