ABSTRACT:
According to the switch of the present invention, a lubricant containing a base oil, a soft resin polymer, and a surface active agent is applied between a fixed tab and a contact strip that undergo sliding operation in response to vertical movement of an operating part. The soft resin polymer of the composition works effective in minimizing wear of the contacting surfaces of the fixed tab and the contact strip. At the same time, including the surface active agent in the composition can prevents the lubricant from flowing to an undesired section. The lubricant with the composition above can provide a switch with a reliable switch-on/off operation.
