Preferable, technique scheme can also be added following technical characterictic:

The described section that touches cap presser is to be one to fall " U " body.

Compared with prior art, adopt the advantage that the utlity model has of technique scheme to be:

One, touch-pressure switch composition member of the present utility model is comparatively simple, and is that electric conductor is one-body molded in elastomeric hollow base, therefore, spends lower at manufacturing processing and cost.

Two, touch-pressure switch of the present utility model is in operating process, because its electric conductor is one-body molded in described elastomeric hollow base, so can be because of the stress deformation or the application of force are inhomogeneous repeatedly, and the situation that is subjected to displacement, and then the stability of touching is led in lifting, make described touch-pressure switch have favorable conductive characteristic and Reliability, and effectively promote its competitiveness on market.
