How to select a switch lock

Determine the electrical requirements for the device being controlled:

  • Voltage (for example: 115 VAC or 24 VDC)
  • Current or horsepower (for example: 6 amps or 1/2 horsepower)
  • Type of load • Resistive (for example, heater elements) • Inductive (for example, motors, large transformers) • Lamp (for example, incandescent lights)

Determine the switch configuration (poles and throws) and key removal condition:

  • Poles To determine the number of poles, find how many wires from the power source need to be switched on and off by the switch lock.
  • . Throws To determine the number of throws, find how many wires to the device the switch needs to control. For example, if a switch needs two different "on" conditions (low and high speed), two throws are needed. Or if the device is simply an "on-off" type (only one wire), you need one throw.
  • . Key removal To determine the key removal condition, ask the question, "When the key is removed, should the switch be "off", or could the switch be either "on" or "off" ?" Although the key can only be removed in the 12 o'clock position, the switch itself may be left in two or three positions. Check each switch lock for key removal switch positions.

Use the information collected and find the switch lock that best meets the requirements

  • Refer to the following catalog pages for a description of each switch lock. If environmental conditions make it necessary that the switch lock be housed in an electrical box, see the Optional boxes below for the box that best suits the switch lock and your application.
