Abstract
An inertia micro-switch includes a shell, a cell unit and an actuator. The shell includes a drum placed between an upper unit and a lower unit. The cell unit is placed in the shell. The actuator includes a housing unit, a lower conductive rod, two movable elements and a hit-taking unit. The housing unit is placed in the vicinity of the cell unit in the shell. The lower conductive rod is placed in the housing unit and connected to the cell unit. The movable elements are placed in the housing unit. The hit-taking unit moves the movable elements and hence contacts the lower conductive rod when it takes a hit.
Claims18
An inertia micro-switch including:
- a shell including an upper unit, a lower unit and a drum 1 placed between the upper and lower units;
- a cell unit placed in the shell;
- and
- an actuator 8 including:
- a housing unit placed in the vicinity of the cell unit in the shell;
- a lower conductive rod 803 placed in the housing unit and connected to the cell unit;
- two movable elements 806 placed in the housing unit;
- and
- a hit-taking unit for moving the movable elements 806 and hence contacting the lower conductive rod 803.
An inertia micro-switch including:
- a shell including an upper unit, a lower unit and a drum 1 placed between the upper and lower units;
- a cell unit placed in the shell;
- and
- an actuator 8 including:
- a housing unit placed in the vicinity of the cell unit in the shell;
- a lower conductive rod 803 placed in the housing unit and connected to the cell unit;
- two balls 806 placed in the housing unit;
- and
- a hit-taking unit including:
- a lower spring 804;
- an inertia ring 805 biased by the lower spring 804;
- an upper conductive rod 807 movably placed in the housing unit, wherein the upper conductive rod 807 moves the balls 806 and hence contacts the lower conductive rod 803 when the hit-taking unit takes a hit;
- and
- an upper spring 808 including an end connected to the upper conducive rod 807 and another end connected to the housing unit.
A method for operating an inertia micro-switch including the steps of:
- connecting a lower conductive rod to a cell unit;
- providing an inertia ring for moving downward and compressing a spring when the inertia ring takes a hit;
- and
- providing an upper conductive rod for moving downward, pushing open two balls normally restrained by the inertia ring, and hence contacting the lower conductive rod.
