PROBLEM TO BE SOLVED: To prevent the sensitivity of a reed switch by mounting a vibrationproof rubber between the reed switch and a component or between the reed switch and an outer case. SOLUTION: A vibrationproof rubber 3 is fitted between a reed switch 1 and a battery or between the switch 1 and an outer case 10. Then the vibrationproof rubber 3 is in existence at both sides of a reed section 2 of the reed switch 1 and the outside of the vibrationproof rubber 3 is inserted between a board 4 and a component 5 so as to allow the vibrationproof rubber 3 to be always compressed. Since a change in the sensitivity of the reed switch 1 is caused by exerting a force from the board 4 to an internal contact 8 of an element tube 7 from a lead 6, the shock is relaxed by retaining the lead 6 at the outside of the element tube 7 with the vibrationproof rubber 3. When the reed switch 1 is not mounted to a fixed board 4, since the effect of shock from the lead 6 is less, the vibrationproof rubber 3 is inserted between the element tube 7 and the component 5 to prevent collision with other components.
