Push button means momentary contact.

Answer is SPDT.
The basic theory is the moving contact of the switch is known as "Pole" & non-moving contact is known as "throw". So, from symbol we come to know that there is a single pole and double throw. Hence it is SPDT.

@Usman : you can take a example of a relay where three terminals are there. Com, NO, NC. When common connects with NO it is open switch.
And when com connects with NC it is closed switch.
And when com connects with NC it is closed switch.

SPDT Is Correct Answer.
SPDT Stand For:
S = Single.
P = Pole.
D = Double.
T = Through.

SPST Single pole, single throw One-way Two-way A simple on-off switch: The two terminals are either connected together or disconnected from each other. An example is a light switch.
SPDT Single pole, double throw Two-way Three-way A simple changeover switch: C (COM, Common) is connected to L1 or to L2.
DPST Double pole, single throw Double pole Double pole Equivalent to two SPST switches controlled by a single mechanism
