STOP LIGHT SWITCH

DESCRIPTION

The stop light switch is an electro-pneumatic switch and

operates in conjunction with the brake valve and stop

lights by completing the electrical circuit when a brake

application is made.

OPERATION

When a brake application is made, air pressure from

the brake valve enters the cavity below the diaphragm.

At approximately 5 psi, the air pressure underneath

the diaphragm overcomes the force of the spring and

moves the piston or plunger until the contact points close,

completing the stop light electrical circuit and lighting the

stop lights.

PREVENTIVE MAINTENANCE

Important: Review the Bendix Warranty Policy before

performing any intrusive maintenance procedures. A

warranty may be voided if intrusive maintenance is

performed during the warranty period.

No two vehicles operate under identical conditions; as

a result, maintenance intervals may vary. Experience is

a valuable guide in determining the best maintenance

interval for air brake system components. At a minimum,

the Bendix

SL-3

™

and SL-4

™

switches should be inspected

every 6 months or 1500 operating hours, whichever comes

first, for proper operation and electrical connections.

Should the SL-3

™

or SL-4

™

switch not meet the elements

of the operational tests noted in this document, further

investigation and service of the valve may be required.
