If it is necessary to replace a spring contact switch or a contact button, extreme care must be taken when installing the new components.
The contact button is replaced by first removing the switch contact, then the contact button. The contact button must be seated against the PC board. The contact button may also be inserted using an AMP hand tool, model number 274262-1. The spring contact may be replaced using AMP tool number 274268-1 or by hand. When inserting by hand, use extreme caution and lightly press on each side-mounting pin of the contact until it is through the PC board. NEVER push the contact into the PC board by pressing on the CENTER of the spring contact as this will misshape it. Note the accompanying insertion diagram.
