Breaker button 701/71400 JCB, aftermarket

For the JCB machines: breaker button 701/71400, an aftermarket part.

This button is listed in the product card as the hydraulic breaker operating button, number 701/71400. With the breaker circuit on, the push button runs the breaker for as long as it is held down, and the breaker stops when it is released. This means the breaker works only when, and as long as, the operator wants. A worn button makes the breaker work intermittently or not at all. The button is fitted to the panel or control lever, and its wire joints must be clean and tight. The button is used often, so its contacts can wear, and its seal keeps dust and water out.

Fitting

Do not wipe cab switches with wet cloths or solvents, since liquid seeps inside and oxidises the contacts. The switch is chosen by part number and its pin layout compared with the old one. If the pins at the back are darkened or melted, check the harness connector too, since a faulty connector will heat the new switch as well. After the change, test the function in every position. Rocker switches are held in the panel by their side clips, and a switch with broken clips can be pushed into the panel when used.
