MIL-PRF-24236/20J
REQUIREMENTS:
Dimensions and configuration: See figure 1 and table I.
Operating temperature range: -10 F to +300 F.
Class: 4, except vibration 10 to 2,000 Hz, 10G.
Mounting: See table I and figure 2.
Weight: Not to exceed 12 grams, including mounting bracket.
Dielectric withstanding voltage: 70,000 feet - 350 V ac.
Operating temperature and tolerance: See tables II, III, and IV.
Electrical ratings: See table V.
Endurance test: See table V.
Low level: When specified, see part number information, 250,000 cycles.
QUALIFICATION:
Single submission: Restricted to switch submitted.
Group submission: See table VI.
Part number: Consists of "M" prefix followed by specification sheet number; a dash (-); and a four letter code.
The four or five letter code identifies the configuration and contact action (code from table I); operating
temperature (temperature to the nearest 25 F, code from table II, and temperature setting to the nearest 5 F
with applicable tolerance, code from table III); and temperature differential (code from table IV). The five-letter
code used in the following example identifies a low level switch of configuration A (figure 1) which closes on
increasing temperature at 140 F 4 F and opens on decreasing temperature 2 F to 5 F below the actual
closing temperature. Use the letter "L" as a suffix for the part number when a low level switch is required.

"M" prefix and specification sheet number
Configuration and contact action = Code "A"
of table I (i.e., configuration A which
closes on increasing temperatures)
Closing temperature = Code "G" (150 F)
of table II and Code "F" of table III
(-10 units with a 4 F tolerance) (i.e.,
150 F, -10 F, 4 F = 140 F 4 F)
Temperature differential = Code "B"
(2 F-5 F) of table IV
Add the letter "L" when low level is
required.
