2. INTRODUCTION

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.

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.

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.

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.

3. SWITCH INSTALLATION

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.

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

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

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.
