How to Wire 2 Limit Switches in Series

A limit switch, otherwise known as an end-stop, is an electrical switch used to control the movement of a machine or device. They can be wired in series, parallel, or even combinations of series/parallel. Wiring two Limit Switches in series can be done with ease using a few basic tools and materials. This article will provide instruction on how to wire two limit switches in series.

When wiring two Limit Switches in series, there are many factors to consider. It is important to know the correct voltage and amperage required for the wiring, as well as what type of connection is needed. Additionally, it is important to ensure that the switches are compatible with one another and that the wiring is correctly connected. To ensure safety, all wiring must be performed in accordance with local electrical codes.

Gathering Materials

The first step in wiring two Limit Switches in series is to gather the necessary materials. The following components are needed: two Limit Switches, each with a mounting screws, conduit connectors, wire stripping tool, crimping tool, wire connectors, and insulated wire. Additionally, it is important to determine the correct size and type of wire needed for the circuit.

Installing the Limit Switches

The next step is to mount the Limit Switches in their respective locations. Ensure that switches are level and securely mounted. Next, the wiring and conduit connectors must be attached to the Limit Switches and secured with the mounting screws.

Stripping and Crimping the Wires

Once the Limit Switches are installed, the wires must be stripped and crimped. Using the wire stripping tool, carefully remove the outer insulation from the wire, leaving the inner conductor exposed. Then, connect the wires to the terminals on the switches by inserting them into the appropriate terminal and crimping them securely.

Wiring the Switches in Series

Finally, the switches must be wired in series. To do this, connect one of the wires from the first Limit Switch to one of the wires from the second Limit Switch. Then, connect the remaining two wires together. Make sure that both switches are off before connecting the wires.

Testing & Troubleshooting

Before completing the installation, it is important to test the circuit to ensure that it is working properly. To do this, turn on the power source and press each switch. If both switches turn on and off correctly, then the installation is complete. If either switch fails to operate properly, then the wiring connections should be inspected for loose connections or incorrect wiring.

By following these steps, the installation of two limit switches in series can be completed quickly and safely. It is important to remember that all wiring must be completed in accordance with local electrical codes and that a professional electrician should be consulted if necessary.
