Kirley Posted December 19, 2012 Share Posted December 19, 2012 I am looking for help on how to wire a micro switch for my lifting bridge. My switch has 3 terminals 1. Is common and connected to one of the bus wires. 2. The other two terminals are classed as normally open terminal (NO) and normally closed (NC) terminal. Do I wire the other bus wire to the normally closed (NC) terminal thus only providing power when the bridge is in the down position? Quote Link to comment Share on other sites More sharing options...
0 Dave Posted December 19, 2012 Share Posted December 19, 2012 Here is a wiring diagram http://www.micromark.com/html_pages/instructions/82611i/82611microswitches.htm Use the normally open contact for the bus, when the bridge is down the switch is open circuit, bridge up circuit closed.

Question
Kirley
I am looking for help on how to wire a micro switch for my lifting bridge.
My switch has 3 terminals
1. Is common and connected to one of the bus wires.
2. The other two terminals are classed as normally open terminal (NO) and normally closed (NC) terminal.
Do I wire the other bus wire to the normally closed (NC) terminal thus only providing power when the bridge is in the down position?
