Abstract
Abstract The point of the pivoted toggle lever acts on the cam surfaces of the spring biased slidable cam to obtain the desired action depending upon the cam configuration. The shorting bar is mounted on the toggle lever for limited pivoting action to insure equal pressure against the contact pins at the extremes of motion. The pins are brought out of the case for simple connection to printed circuit boards. All parts are mounted in and retained by the case halves which are identical and snap together.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
158 words
A toggle switch comprising: a. a housing; b. a lever including a pivot post on opposed faces thereof journaled in recesses in the housing to permit movement of the lever to an active position on either side of a medial position; c. a cam block slidably mounted in and guided by a cavity in the housing; d. a spring biasing the block into contact with the end of the lever; e. said cam block having a cam surface against which the lever end acts and contoured to retain the lever in or return the lever from its various positions; f. a pair of stationary contact pins parallel to the pivot post and mounted in the housing on both sides of the lever and having ends projecting through the housing; and g. a shorting bar carried by the lever and operative to bridge either of said pairs of contacts when the lever is in either of said active positions.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
45 words
A toggle switch according to claim 1 in which said shorting bar is mounted on the lever for limited rotation relative thereto to assure proper contact with both contact pins of each of said pairs when the lever is in Either of said active positions.
Claim 4
Dependent Claim
21 words
A toggle switch according to claim 2 in which the housing serves to retain all the switch parts in assembled position.
Claim 5
Dependent Claim
43 words
A toggle switch according to claim 3 in which the housing is comprised of two halves which snap together, said pins being mounted in cooperating holes in the housing and having a shoulder at the interface of the halves for retaining the pins.
Claim 6
Dependent Claim
49 words
A toggle switch according to claim 1 in which the lever has a raised boss thereon upon which the shorting bar is mounted, said bar having an arcuate notch generally loosely conforming to the adjacent pivot post while allowing restricted motion to seat the bar on the contact pins.
