Abstract
Abstract In an indicating instrument, a plurality of measuring elements (2,3) are fastened in axially displaceable manner on a base plate (1) and held by compression springs (4,5) against a front plate (6) of a housing (7). The measuring elements (2,3) are provided on their rear with contact pins (9,10,11) which pass through a base plate (1) of the indicating instrument and, behind it, engage, in each case, in a plug-type receiver (12,13,14) of a circuit board (15).

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
104 words
An indicating instrument comprising at least one measuring element; a circuit board; a base plate and a front plate between which said at least one measuring element is fastened, the measuring element having contact pins to be passed through the base plate for contacting the circuit board, the circuit board extending behind the base plate; at least one compression spring; and wherein the measuring element is held by the base plate and said at least one compression spring, said at least one compression spring allowing transverse displacement of the measuring element along the base plate and clamping the measuring element against the front plate.
Claim 2
Dependent Claim
104 words
An indicating instrument comprising at least one measuring element; a circuit board; a base plate and a front plate between which said at least one measuring element is fastened, the measuring element having contact pins to be passed through the base plate for contacting the circuit board, the circuit board extending behind the base plate; at least one compression spring; and wherein the measuring element is held by the base plate and said at least one compression spring, said at least one compression spring allowing transverse displacement of the measuring element along the base plate and clamping the measuring element against the front plate.
Claim 3
Dependent Claim
19 words
An indicating instrument according to claim 1, wherein the circuit board has plug-in sockets for contacting the contact pins.
Claim 4
Dependent Claim

Claim 5
Dependent Claim
41 words
An indicating instrument according to claim 2, further comprising guide pins secured to the measuring element; and guide sleeves secured to the base plate; and wherein the measuring element engages the base plate via the guides passing over the guide pins.
Claim 6
Dependent Claim
39 words
An indicating instrument according to claim 1, wherein guide sleeves secured to the measuring element; and guide pins secured the base plate; and wherein the measuring element engages the base plate via the guides passing over the guide pins.
Claim 7
Dependent Claim
41 words
An indicating instrument according to claim 1, further comprising guide pins secured to the measuring element; and guide sleeves secured to the base plate, and wherein the measuring element engages the base plate via the guides passing over the guide pins.
Claim 8
Dependent Claim
71 words
An indicating instrument according to claim 1, further comprising a support pin protruding from the base plate, and a second compression spring; and wherein the two compression springs comprise a total of two rubber caps for each measuring element, the front sides of the caps resting against a rear surface of the measuring element, the caps being placed on the free end of the support pin prortruding from the base plate.
