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 SL-3

™

SL-4

™

switch should be inspected every 6 months or 1500

operating hours, whichever comes first, for proper operation

and electrical connections. Should the SL-3

/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.
