Installation

Figure 14 Microswitch Assembly

1. Install the plunger on the M6 stud as show above.
•
2. Screw the plunger down until it is 5mm below the back of the magnet.
3. Slide the Microswitch assembly into place with the anti-rotation wire behind the plunger
as shown below.
4. Fasten the assembly with a single M6 hex head bolt using a 10mm wrench/socket.
5. Connect the Microswitch leads to a digital multimeter and set the meter to diode test
settings. The meter should read OL indicating an open switch connection.
•
•
6. Attach the lead wire to a power supply with the correct voltage for the brake and turn the
power on. This will pull the armature flush with the magnet.
•
7. Adjust the plunger out using an 8mm open end wrench until the plunger contacts the
Microswitch lever as shown below.
•

The microswitch is typically mounted on the lead wire side of the magnet.

Microswitch black to blue = normally open.
Microswitch black to grey = normally closed for reverse logic use.
Alternately: Tighten the two manual release bolts until the armature is pulled flush
with the magnet to simulate active power.
The terminal strip on the Theater Load Brake can be used for Microswitch
connections.
