The push-on terminal is a small electrical connector on the end of a wire. Push-on terminals connect wires to the switches and relays inside a kiln. Do not use the terminals and wire sold in hardware stores. Kilns require high-temperature parts.
When replacing a part such as a switch, also replace the push-on connectors that have been damaged by heat. The push-on terminal should be tight.
If the push-on terminals are on so tight that they are difficult to remove from the switch, grip the terminals with needle-nose pliers.
Push the terminals onto the blades of the new switch or relay as far as the terminals will go. The push-on terminals must be fully seated on the blades of the new part. Again, use pliers to push the terminals into place. Make sure the wires are securely fastened to their terminals. A loose wire can destroy a new relay or switch by arcing and overheating.
