2. INTRODUCTION
3. SWITCH INSTALLATION
The SPST and MPMT switches are available in 2
through 12 positions. They can be used in DIP
sockets with in--row contact centerline spacing of 25.4
[.100] and row--to--row contact centerline spacing of
7.62 [.300], or they can be soldered directly to the
printed circuit (pc) board.
Determine the number of switch positions required for
your application. Determine whether the switch will be
soldered directly to the pc board ( a sealed switch will
be required), or whether the switch is to be installed in
a socket (an unsealed switch can be used). Refer to
the tables in Figures 1 or 2 for assistance in selecting
a switch.
There are standard--profile, side--actuated, and low--
profile SPST switches. The standard--profile switches
have raised rockers, and are available unsealed, or
sealed with an economy or premium masking
material. The side--actuated switches have rockers on
the side rather than on the top, and are available
unsealed, or sealed with an economy or premium
masking material. The low--profile switches have flush
rockers, and are available unsealed, or sealed with an
economy clear tape, or sealed with a premium
masking material.
3.1. DIP Socket Installation
1. Secure DIP socket to pc board according to
instructions packaged with socket.
2. Start one row of contact leads into one row of
contact cavities in socket, then rotate switch until it
is parallel with socket.
3. Gripping ends of switch, push switch into socket
until it is bottomed
There are standard--profile and side--actuated MPMT
switches. The standard--profile MPMT comes in both
Single--Pole Double--Throw (SPDT) and Double--Pole
Double--Throw (DPDT) make--before--break switches
and are available with a low--profile and extended
lever actuator. The side--actuated MPMT is available
in SPST only at this time. All of these switches are
available in the unsealed version only.
4. Determine which of the circuits are to be closed,
then depress the applicable rockers to the ON
position.
5. If installing a protective dust cover, determine
the number of switch positions and refer to
The unsealed switches are designed for socket
applications and the sealed are designed for soldering
applications directly to the pc board. The sealants
prevent flux and other contaminants from entering the
switch during soldering and cleaning.
Customer Drawing 435238 to select the applicable
cover. Check to be sure there are no obstructions
on the switch rockers or in the protective cover,
then slide the cover over the rockers until the cover
latches engage the housing. See Figure 3.
