Abstract
An electronic component comprising: a case; a switching mechanism incorporated within the case; an actuator configured to actuate the switching mechanism, the actuator being mounted in the case so as to be displaceable by sliding; and a rubber cap configured to seal a sliding part of the actuator, wherein the rubber cap is made of a hydrin-based rubber.
Claims5
An electronic component comprising:
- a case;
- a switching mechanism incorporated within the case;
- an actuator configured to actuate the switching mechanism, the actuator being mounted in the case so as to be displaceable by sliding;
- and
- a rubber cap configured to seal a sliding part of the actuator,
- wherein the rubber cap is resistant against a permeability of siloxane gas and is made of a hydrin-based rubber;
- wherein the hydrin-based rubber consists essentially of epichlorohydrin homopolymer or epichlorohydrin-ethylene oxide copolymer or epichlorohydrin-ethylene oxide-allyl glycidyl ether terpolymer;
- and
- wherein an ether-based plasticizer is added to the hydrin-based rubber in an amount of 5 to 40 parts by weight based on 100 parts by weight of the rubber.
